INOANDESCENT-I-LAMP SOCKET.

Specification of Letters Patent.

Patented Nov. 27, 1906.

Application filed Icy 12,1906- Sarial No. 816.627.

To all whom it may concern:

Be it known that I, WILLIAM W. -JoNns, a citizen of the United States of America, residing in Bridgeport, in the county of-Fairfield, in the State of Connecticut, have invented certain new and useful Improvements in In-- candescent-Lam Sockets, of which the fol lowing is a-spec' cation.

- My mventlon relates to the construction of incandescent-electric-lamp sockets and the like; and the object of my invention is to provide a means whereby the cap and shell may be readily and securely attached together and as readily detached when desired.

In the accompanying drawin s, Figure 1 is a side elevation of the socket, s ell, and cap detached from each other. Fi 2 is'a view of the irmer face of the cap; and ig. 3 is a section of the cap, taken on the line 3 3, Fig. 1.

A is the shell, and B is the cap, preferably made of drawn sheet metal, as usual. The ca has a flange 0, within which the shell fits.

y-means of fastening the shell and cap are as. follows: Bayonet-joints between the shell and cap may be made by means of'suitable projections 5, diametrically opposite each other on the shell and which fit in rightangul'ar ooves or cuts 6, having corresponding positions in the flanges of the cap. Revolutlon of the parts after they have become locked by the bayonet-j oint described may be prevented by a tongue-spring], cut. in the flange of the cap and provided on its inner face and near its free end with a rojection 10, which engages a corresponding hole 8, cut in the shell at a suitable point. The top of the tongue is bent up at 9 to permit its being lifted, whereb the projection may be withdrawn from t e hole in the shell. The cap may then be rotated and the bayonet-joint freed for removal of the cap.

. I claim as m inventi0n 1. An incan escent-lamp socket or the like, having a cap and shell detachabl connected, one 0 said parts having angle notches or grooves engaging with projections borne on the other part, and a s ring-tongue cut in the flange of the cap, wit means to engage the spring-tongue with the shell to prevent rotary motion.

2. An incandescent-lamp socket or the like, having a cap and shell detachably connected, the caphavmg angled ooves engaging with projections borne on t e other part, and a ton e cut in the'flange thereof having a roj ectlon which engages in a hole in the she I to prevent rotary motlon.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

. I WILLIAM W. JONES. Witnesses:

I G. W. GooDRmGE, F. E. SEELEY.
